Assumedly all the story quests between 2.1-2.55 will be giving exp come expansion, it would be kind of wierd if they didn't at that point. They don't right now because there would be no point to it since we are at cap when we did them/are doing them right now. Still my personal opinion that by SoF new players would about lvl 53 which would be about equivilent with ilvl 90, with gear that should be around that level and most importantly, base stats that have increased which can make a good bit of difference.
